Heat 2 tbsp oil in pan, when it is hot enough at whole spices (2 black cardamom, 1 green cardamom, 6-7 cloves, 7-8 small pieces of cinnamon) and cumin seeds. Fry a bit and add curry leaves, onion paste (1 large) and stir well. Add salt and cook the onion paste till it is nicely cooked and golden in colour. Add 1 tbsp ginger garlic paste, 1 tsp chopped/ crushed green chillies and mix well. Add pinch of hing, turmeric powder, red chilli powder, coriander powder, garam masala and 1 cup tomato puree and mix all the ingredients well. Add 2 tbsp paste of cashew nuts and watermelon seeds, add little water, 1 tbsp yoghurt and cook this mixture till it oozes out oil. Cover with lid and cook for few mins. Add in the fried vegetables (capsicum, potatoes, paneer, cauliflower florets, peas and carrots) which were cooked till 95% done. Cover and cook for another 3-5 minutes. Add the fruits (apple, pineapple, grapes and pomegranate seeds) and mix well. Adjust the consistency by adding little water and bring it to one boil and the korma is ready. Top it with little ghee (optional). Sprinkle some coriander leaves and switch off the flame.
